To all who m it may concern:

BeitknoWn that we, WALTER E. Eeenns TON and LEON L. CHAUNCEY, citizens of the lnited States and residing at Binghamton, in the county of Broome and State of New York, haveinvented certain new and useful Improvements in Fireproof Film-Rewindcrs, of which the following is a-specification. Our invention relates to fire-proof film rewinders for rewindingr films inmoving picture shows, free from'the dangers incident to being exposed to fire or electric sparks and in which films in being unwound are inclosedin a metallic fire-proof case, the rewinding being accomplished by exterior connecting power, either hand power or mechanical power, and the means being always afforded for examination of the film while inclosed in the fireproof case during the period of unwinding.

With these objects in view our invention consists in certain novel features of construction and arrangement of parts as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawings in'which' Figure 1 represents a front view of our device partially'in cross section mounted on a platform and with film inclosed. Fig.2 represents an end view of our device partially in cross section. Fig. 3 represents a fragmentary part of a rear elevation of our device.

The same reference characters denote like parts in each of the several figures of the In carrying out our invention we provide a body portion A with curved outline and having the rim 2 forming the curved sides of the chambers or interior parts 3. 3'. The rim 2 having also on its edge at the opposite curved portions the hinged projections 4. 4. Conforming to the curved rim forming interior chambers 3. 3 we have the hinged doors 5. 5 having the hinged projections 6. 6. In the upper portion of rim 2 we have the window or opening 7 in which a glass is mounted and on the narrow portion of the lower curved rim we have an opening or window 8. The body A projects into a vertical supporting standard B as shown in Figs. 1 and 2. Mounted in the standard B we have the shaft 9 and mounted on said shaft 9 we have the crank handle 13. Projecting from the front face of standard. B

' we have the bracket or brace formation 10. Projectlng from thelower end of standard B we have the foot projection 11 having in it openings for screws 12. 12-. or other means for fastening it to thefsurface of shelf 12.

Mounted in the interior. of the curved rim 2 we'have the small rollers13'. 13- shown in Fig.1 for contact with the winding film 20.

Mounted on the rear end of shaft 9 we have the pulleys 14 and 15 the small pulley 15' being for the purpose of attaching a belt connected with outside mechanical power for turning shaft 9. Mounted in chamber 2 we have a turn shaft '16 on the rear end of which we have mounted a small pulley 17 and in chamber 31 we have mounted a shaft 16'. The-hinged doors 5. 5"operating on hinges with the rim at 6; when closed their inner edges meet onthe line 18. Between pulley 14 andpulley 17 we have extending the belt 19'. i

In the operation of our device we open the doors 5. 5 and mount the reel to be unwound on, shaft 16 in chamber 3' and we mount the reel C to be wound upon shaft 16. We pass the-end of the film 20 over the rollers 13'. 13- and extending from the reel on shaft 16' up over the pulleys 13. 13 and attach it to the reel on shaft 16.

We then close the doors 5.. 5. W e then turn crank 13 which turns pulley 1 L which-by means of .b'elt 19turns pulley 17 causing the reel onshaft 16 to revolve winding upon it film 20 from the reel on shaft 16 and continuing inthis way until the entire film is =unwound from the one reel and wound upon the other; the entire apparatus being safely inclosed within the metallicinclosure: 'Bei low the windows 7 and 8 and'mounted on the face of the standard B, in; any convenother or we can attach a belt to pulley 15 connected with outside mechanical power and thus byv means of mechanical power wind and unwind the films.

Having thus described our invention what we claim1 as new and for which We desire Letters Patent is as follows;

1. In a device of the class described, a

casing open at its front and formed with.

sageway, said passageway conducting the film from one reel to the other, anti-friction rollers at each end of the passageway, and

a pair of hinged doors for closing the open end of the chambers, said doors eing provided with extensions to close the open end of the narrow passageway.

2. In a device of the class described, a casing open at its front and formed of two spaced chambers connected together at their upper ends by a narrow passageway, said chambers being adapted to receive t? e film reel and the passageway serving to conduct the film from one reel to the other, alining sight openings in the top and bottom Walls in the passageway, and illuminating means the space between the two chambers.

3. In a device of the class described, a casing open at its front and formed with two spaced chambers each adapted to receive a reel, said chambers. being connected at their open ends by a narrow passage way, said passage way conducting the films. from the reel in one chamber to the reel in the other chamber; a pair of hinged doors for closing the open fronts of the chambers, said doors being provided with meeting extensions to close the open front of the narrow passage way.

In testimony whereof, we have aflixed our signatures in the presence of two witnesses.
